All the Al-Qaeda and Saudi terrorists who come across the Mexican border, the hundreds, if not thousands, of them aren't interested in a 9/11 attack. They want a weekly attack that will poison a water supply, release a deadly gas on a subway, burn a railroad tank car full of really deadly stuff, block some key roads, call in multiple bomb scares (only a few of which are real), or blow up a remote but key bridge/viaduct/power line.
Attacks of this type, conduct at regular, predictable intervals will cancel out our military might and make the neocommunists and their running dogs in the left wing media SCREAM, "we've brought this on ourselves and only a new direction can make it stop."
Until we seal the Mexican border and start a vigorous campaign of checking folks to ensure the belong here and returning those that don't, next year's attacks are CERTAIN!
